What browser do you use on your Mac?

I've been using Safari since I got my mac at the end of 2013. It's super-smooth scrolling just did the trick for me. However, I just recently remembered the smooth scrolling flag in Chrome, so I enabled it today and have been using it since. It seems 90% smooth while Safari is more like 98.7%. I also missed the Notifier for Twitter extension. What do you all prefer?
